摘要：

The activation parameters were determined for the permanent allylic rearrangement (PAR) in five organoboranes of allylic type by means of complete line shape analysis for the dynamic NMR spectra. The introduction of the second boron atom into the allylborane molecule leads to a significant decrease in the activation barrier of the PAR.
